The following example sets a form's RecordSource property to the Customers table:
Forms!frmCustomers.RecordSource = "Customers"
The next example changes a form's record source to a single record in the Customers table, depending on the company name selected in the cmboCompanyName
combo box control. The combo box is filled by an SQL statement that returns the customer ID (in the bound column) and the company name. The CustomerID has a Text data type.
Sub cmboCompanyName_AfterUpdate()
Dim strNewRecord As String
strNewRecord = "SELECT * FROM Customers " _
& " WHERE CustomerID = '" _
& Me!cmboCompanyName.Value & "'"
Me.RecordSource = strNewRecord
End Sub
